Cryptocurrencies have been impressing the world for a few years so far, and the majority of people still do not know the origins of such technology. For the first time, something like a modern blockchain technology was created back in 1998 and found its first implementation by the year 2009. If one had invested in Bitcoin, for example, the year it was firstly available, this person would now be richer by $50 million.

The ICO (Initial Coin Offering), which is basically same as IPO but with cryptocurrencies is now prohibited in China. Unauthorized fundraising is a criminal offence since the Chinese ban put a block on trading and mining. However, Chinese authorities are quite enthusiastic about the blockchain technology, which lies in the basis of cryptocurrencies.

However, it is still not clear whether such currencies stay afloat even in a few years time. Among the main obstacles preventing these from converting into a universally and easily usable ones are regulatory frameworks, poor cybersecurity, an extensive energy consumption.
